start the protected-mode command interpreter ("Start a Program") or the real-mode command interpreter ("command.com").

+From PC Magazine, July 1986, by Charles Petzold:
+
+> ### DOS GETS BETTER--AND MORE EXPENSIVE, TOO
+
+> #### DOS 3.2 adds new commands and a unique device driver and makes some minor changes.
+
+> As usual with new PC-DOS versions, PC-DOS 3.2 has been released in conjunction with a new product (the PC
+Convertible), but it can run on all previous members of the IBM PC family. PC-DOS 3.2 is available on either one
+3-1/2 inch 720K-byte disk or two 5.25-inch 360K disks. These disks include everything in PC-DOS 3.1, plus three new
+programs. At $95, PC-DOS 3.2 is the most expensive PC-DOS yet.
+
+> The shining star of the new PC-DOS is XCOPY, a fast file-copy utility that combines features of COPY, BACKUP,
+and RESTORE. XCOPY is fast because it reads as many files as possible into available memory and then writes them
+out to the target. (COPY and BACKUP, on the other hand, have to continually alternate between the source and target
+drives for each file they copy.)
+
+> Like COPY, XCOPY has /V switch to verify all file writes. Like BACKUP, it has /M and /D switches to restrict copying
+based on file modification of the file date. A /S flag lets XCOPY find files in nested subdirectories and create the
+subdirectories on the target disk if they don't already exist. A /P switch prompts you with a "Y/N?" for each file,
+and a /W switch lets you swap disks before XCOPY starts up.
+
+> You can also use XCOPY as a backup utility. The advantage over BACKUP is that the copied files are directly usable.
+On a Bernoulli Box attached to a PC, I XCOPYed over 1,200 files from one 10-megabyte cartridge to another in just under
+15 minutes. The bonus, of course, is that the fi1es are unfragmented on the target cartridge. However, XCOPY's
+usefulness for backing up hard disks is diminished by two problems: first, it does not recognize hidden files, which
+are used by many copy-protection schemes, and second, it has no built-in provision for changing target disks when they
+become full. (You can get around this second problem by using the /M switch and repeatedly running the same XCOPY
+command for different target disks.)
+
+> The second new program in PC-DOS 3.2 is REPLACE, yet another file copy utility. REPLACE can replace all copies
+of a particular file (which may be located in various subdirectories of a hard disk) with a new version. Using a /A
+switch adds the source files to the target without overwriting existing files. The manual recommends using REPLACE
+after a SYS command when upgrading an existing machine to DOS 3.2.
+
+> The third new program is DRIVER.SYS, a device driver that can be included in your CONFIG.SYS file. It lets you create
+a new logical disk drive letter that references the same physical disk as an existing disk drive letter. This type of
+thing happens automatically on a PC with only one disk drive: logical drive letters A and B both refer to the same
+physical disk drive. DRIVER.SYS lets you do the same thing for another drive. This is most useful when installing the
+external 720K-byte 3-inch disk in a PC, XT, or AT. By using DRIVER.SYS to give this disk drive a second drive letter,
+you can XCOPY files from one 3-inch disk to another using the same physical drive.
+
+> PC users who have been getting an "Out of environment space" message after executing a few too many SET commands
+from batch files need no longer resort to patches or undocumented COMMAND.COM switches. If you specify COMMAND.COM
+as a SHELL program in your CONFIG.SYS file, you can use the /E switch to specify your environment size up to 32K bytes.
+Note that this is the same switch that worked (but was undocumented) in DOS 3.1, but the DOS 3.1 switch required a
+16-byte paragraph environment size instead of bytes.
+
+> Some smaller changes: FORMAT and DISKCOPY now support the 720K-byte 3.5-inch disk format (of course).
+FORMAT 3.2 will not run unless you give it a drive letter parameter--an added barrier to accidently formating your
+hard disk. ATTRIB 3.2 lets you manipulate the archive attribute of files as well as the read-only attribute.
+
+> The elongated shape of the PC Convertible display may make printing graphics screens on the printer a problem.
+You may want printed graphics to look the way they do on the Convertible display or as they would appear on a normal
+display. The GRAPHICS 3.2 resident graphics screen print program lets you make this decision yourself.
+
+> The disappointing aspects of PC-DOS 3.2 are its omissions. Although Microsoft has stated that future versions of
+MS-DOS will support the Lotus/lntel/Microsoft Expanded Memory Specification, that support is not included with PC-DOS
+3.2. ANSI.SYS 3.2 still does not support the Enhanced Graphics Adapter (EGA) in 43-line mode or for video pages other
+than page 0. No changes at all have been made to ANSI.SYS.
+
+> Although documentation for BASICA 3.2 did not reach the editorial offices of PC Magazine, some creative
+DEBUGing and experimentation reveal five new BASICA commands. Three of these commands are EXTERR, LOCK, and UNLOCK,
+corresponding to the extended error-handling and file-locking and unlocking functions of DOS 3.x. Another new BASICA
+command is PCOPY, which lets you copy one video page to another.
+
+> BASICA 3.2 also includes some support for the EGA, but this support is so minimal that it is likely to infuriate
+BASIC users. The PALETTE command lets you manipulate the EGA palette registers so that you can map default colors to
+other colors. This is particularly useful in medium-resolution mode because it means you're no longer stuck with the
+same two sets of three colors.
+
+> The PALETTE command is the extent of EGA support in BASICA 3.2. In fact, the SCREEN and PCOPY commands do not even
+recognize the additonal video pages in the EGA's 80-column text mode. Support of the EGA graphics modes is nowhere to
+be seen.
+
+> PC-DOS 3.2 gives the PC user a couple of extra tools that would certainly be worth a $30 update charge.
+Unfortunately, there is no update policy for DOS, so you'll be shelling out the full $95 for it. That's obviously too
+much money. But for those who spend many hours at their PCs, keeping up with the latest DOS version comes with the
+territory.

+### OS/2 1.0 Debugger Boot Disk
+
+The [OS/2 1.0 Debugger Boot Disk](/disks/pc/os2/misc/1.0/debugger/) contains a version of OS/2 1.0 built on
+October 12, 1988, which includes the built-in kernel debugger used by Microsoft and IBM for internal development.
+For more details, see the "OS/2 1.0" [blog post](/blog/2014/12/04/).
+
+Note that IBM OS/2 1.0 was released in December 1987, nearly a year before the timestamps of these files, suggesting
+that this was a private build of IBM OS/2 1.0. When this disk boots, it displays:
+
+ IBM Operating System/2 Version 1.00
+ (C) Copyright IBM Corp. 1981, 1987. All rights reserved.
+ (C) Copyright Microsoft Corp. 1981, 1987.
+
+ 88286
+
+The 5-digit number indicates the day the files were built. The first 2 digits are the year (88) and the 3 remaining
+digits are the day of the year (286 or October 12).
+
+A directory listing of the disk is provided below.
+
+Aside from the fact that this version of IBMDOS.COM is much larger than the 1987 version (thanks to the inclusion of
+the kernel debugger), most of the file sizes are identical. But not all. For example, the 1987 version of CLOCK01.SYS
+is 2762 bytes, whereas this version is 2812 bytes. So apparently a few changes were slipped into the 1.0 sources used
+to build these binaries.
